Paper Abstract

Collimator is an important equipment with high accuracy in optical experiment and measuement. In order to improve measuring accuracy, based on the particular aberration property of diffraction optical element, hybrid refractivediffractive aberration correction method is put forward. In this paper, a hybrid refractive-diffractive method is compared with conventional method with 80mm diameter, 500mm focal length and 550mm overall length. The resolution is less than 4.3". Having been optimized, the maximum spot is 5.2μm, and the modulation transfer function (MTF) at 50lp/mm is over 0.8, better than conventional method.
